I can not unlock the bootloader I enter everything as in the instructions for fastboot flash recovery cwm_6.0.1.0.img, and he writes first sending "recovery"<6480kb>and then filed<remote: bootloader is locked.>help me please.

Well, first open the bootloader, and then later on the neck recovery

[Naruga]

Please tell me how to connect a USB flash drive, so that the Russian language is supported.
I'm on the PC, on Windows, copied files that contain Cyrillic. On the tablet I made root, installed StickMount, connected a USB flash drive, using Total Commander or Root Explorer I go to the appropriate folder and instead of the Cyrillic characters the characters ???. What am I doing wrong?

[anFo]

Naruga,Most likely it is in the kernel (there is no Cyrillic support), but try another program (this, eg)

[insider92]

And what is Paranoid based on? Patched stock? Or something independently collected from sorts?

[anFo]

And what is Paranoid based on?

CM10

[insider92]

Is he not yet what horror alpha bagovannaya?

Is he not yet what horror alpha bagovannaya?

It works perfectly on GN (you can even read a review in the phone branch). I think there is a similar situation.

[anFo]

[email protected], 21:53

How can I increase the time of the tablet in real use?

Kill unnecessary applications (at startup too), select the desired governor, reduce the supplied voltage to the processor, reduce the CPU and GPU frequencies.

[insider92]

Is it possible to somehow force it to use only the 5th core? Those. roughly speaking two modes: economical (5th core) and productive (the rest 4re). Hands to switch modes. Those. if the internet is simple, then the 5th is enough. And if the video or the game is so complicated, then include productive one.

[anFo]

insider92,You can also try. On GN, you can forcibly disable one core through the utilities of kernel developers.

[insider92]

anFo
SetCPU? CPU Master? What do you advise? What can reduce the frequency of the GPU?

[anFo]

insider92,for CPU, I think SetCPU will do (although you can try another one). But for the GPU I do not know. Most likely this possibility is in the utilities of the developers, if, of course, they have the ability to change the frequencies of the GPU in their cores.

[anFo]

DaTa541,Non-working lights in the recovery is not a marriage. Although if the marriage, then something special.
Tried to put TWRP?

[DaTa541]

anFo @ 08/15/2012, 09:08

DaTa541, non-working backlight in the recovery is more likely not a marriage. Although if the marriage, then something special.

Yes, I put all 3 rekoveri from the cap. In all the backlight does not work.
The problem is as described here:http://www.androidcentral.com/nexus-7-disp...auto-brightness
When the first time turned on - it was also not visible, then the flashlight brought to the sensor and the brightness increased. And nothing helps in rekoveri.
Ie definitely a problem with the auto-brightness sensor. A software or iron - I do not know. : x

[anFo]

hor1975,I think there is one way, if you have enabled USB debugging. Otherwise, you can make a nandroid backup, and then pull data from it through TiBu.
If debugging is enabled, I will write how I managed to get around this (albeit GN) in a similar situation.

[anFo]

hor1975,Initially, I came across an unlock method with some application, but the Reset the phone button confused me in the application, and the screens confirmed the thought: it would just reset everything. But with this button it was possible to use another loophole.

1. First you need to download the application.crack_screenlock.apk(96.26 KB)
and put it next to adb;
2. Next, connect the tablet to the computer and open the command line on the computer;
3. In the command line, go to the folder with adb and enter the command:adb install crack_screenlock.apk
The application should be installed, at the end you will see the word "Success", indicating the success of the operation
4. Then enter another command:adb shell am start -n com.test.adm / .UnlockerActivity
The application will open with a single button "Reset the phone".
5. You do not click on it, but simply pull out the notification panel and click on the "Settings" button
6. Well, when you enter the settings, you can turn on Wi-Fi and turn off the graph. key
